Hastelloy G3 is a high-performance alloy. It provides a reliable solution for severe corrosion. Standard tubos de acero inoxidable y accesorios de tubería de acero inoxidable often lacks the needed endurance. This is especially true with reducing acids. This is where Hastelloy G3 offers a superior solution.
What is Hastelloy G3 | UNS N06985
Hastelloy G3 is a aleación de níquel, cromo y hierro. It belongs to the Hastelloy family. It has a high nickel and chromium content. This gives it excellent resistance. It battles hydrochloric, sulfuric, and phosphoric acids. It also offers great thermal stability. This is especially true at high temperatures.
Key Advantages of Hastelloy G3
Hastelloy G3 is very strong, it resists non-oxidizing acids and handles hydrochloric and sulfuric acids well.
It is stable under heat , resists sensitization. This means its corrosion resistance stays strong after welding.
This alloy is easy to form , can be readily welded. It ensures strong, reliable joints for piping systems.

Hastelloy G3 in Piping Systems
- Chemical Processing: Used for handling hydrochloric acid, it resists boiling sulfuric acid.
- Pollution Control: Used in flue gas desulfurization systems, it resists highly corrosive acidic condensates.
- Agro-Chemical Industry: Aggressive pesticides and fertilizers. This alloy resists a wide range of chemicals.
- High-Temperature Systems: Shafts, valvulas, and fasteners. It maintains its properties at high temperatures, the thermal stability is a key factor.
- Piping Systems:Pipes and fittings. These parts need extreme corrosion resistance.
Sourcing and Fabricating Hastelloy G3
Always ask for a Informe de ensayo de materiales (MTR). This proves the material is what it should be.
Trabajar con specialized suppliers of stainless steel pipe and fittings. They understand these alloy steels and can ensure proper fabrication and quality control,and are ISO 9001 y CE-PED certified.
This alloy needs specific welding methods. Make sure your team knows how to handle it.
It’s more expensive upfront. But it lasts much longer. This saves you money in the long run.
